In another blow to Prothena’s neurodegenerative disease portfolio, anti-amyloid candidate PRX012 has run into the same problem that larger peers Biogen and Eli Lilly have battled: high rates of swelling in the brain.
AMX0035—approved as Relyvrio in 2022 for amyotrophic lateral sclerosis but voluntarily pulled from the market last year—was unable to distinguish itself from placebo in a mid-to-late-stage trial of progressive supranuclear palsy.
Novartis has bet up to $772 million to gain access to BioArctic’s BrainTransporter platform, which was leveraged in a partnership with Eisai to produce Leqembi.
Eli Lilly drops a second Phase III readout for orforglipron; AbbVie committed to the psychedelic therapeutics space with the $1.2 billion acquisition of Gilgamesh’s depression asset; the CDC taps vaccine skeptic Retsef Levi to lead its COVID-19 immunization working group; and the FDA prioritizes overall survival in cancer drug development.
LB Pharma will test the IPO market to seek funding for a Phase III-ready schizophrenia asset.
The deal extends AbbVie’s commitment to the psychedelics space and depression, after emraclidine’s high-profile flop in schizophrenia last November.
The platform strategy of using one molecule to target an underlying biological pathway to address many different diseases can be a goldmine for smaller companies. But it also has a unique set of challenges.
The small molecule, vatiquinone, had already flunked a Phase III trial, but the company pushed ahead with an approval bid anyway.
Waltham, Massachusetts–based Skyhawk Therapeutics has been collecting collaborations with larger companies in spades since launching in 2018.
Arguably the FDA’s most anticipated decision this month is for a subcutaneous induction formulation of Biogen and Eisai’s Alzheimer’s drug Leqembi, which, according to Eisai, could “help reduce the burden on healthcare professionals and patients.”
